+Changes from Rev.A / TODO:\n [x] remove FPGA from JTAG chain\n [x] remove SNES IRQ_DIR+IRQ, replace with IRQ_OE. IRQ is unidirectional cart -> console\n      (replace 1gate w/ transistor)\n [x] disconnect P2.10 from FPGA, using a different GPIO for IRQ / INIT_B\n [x] add pullup to P2.10\n [ ] add JTAG pullups\n [x] add series resistor for CPU_CLK\n [x] add a jumper in PIC MCLR line to MCU\n [x] change PIC to DIP8 type for easier preprogramming\n [x] change "P1" to "P401" in pin description in silk screen\n [x] filter CIC data lines\n [x] rearrange SD card interface/LEDs on MCU\n [x] RAs for SNES signals?\n [x] reroute/add decoupling capacitors\n [x] filter SNES control signals (RD, WR, PARD, PAWR, CPU_CLK, IRQ)\n [x] replace 4Mbit SRAM with much cheaper TSOP-II type\n [x] add inverse polarity protection\n [x] separate GND plane for DAC\n [ ] separate JTAG pads for FPGA\n [x] add USE_BATT jumper\n [x] move PROG_B to P1.15
